ENT i OFFICE" ELY RI oriio, AssIGNoR- To THE Fox rURNAcE .coMrANn or ELYRIoHIo, Al conrona'rron or oHIo i n inventionrelates to new and-useful imlprovements inlclosure structures, and more particularly to-the closure supporting means; M An object of Imy invention is to provide means whereby a closure member may be readily attached to and removed from its supporting Structure. Y

Another object is to provide'a supporting means which 4 is concealed from view when the closure member is in closed position. The invention consists in the improved construction and combination of'parts, to be more fully described hereinafter, and the novelty of which will be particularly pointed outand ing horizontal top and-bottomimembersnlQ, respectively, which-are joined by verticalfside members 11, 12.- Extending'forwardly from the member V opening- 8, is a surrounding flange 13. That portion, designated 14, of the-flange 13 which extends along the side bmember 12, is recessed on its rear side and provides'downwardand upward facing shoulders 15, 16, respectively. Through the side member -12`is a` substantially rectangular opening-17 of'aheight substantially equal f to the distance. between the shoulders' 15 and 16. :Surroundingftle Opening 1-7 member' compris'mg substantially; parallel vertical side portions 18, 19, which are joined by top and bottom -portions 20, 21, respectively.

For the purpOse zontal plate members 26,- 27, respectivel solely of illustration, I have shown the strucwhich also extend forw'ard' ture 1 as a portion of aheatingapparatus of stantially equal to that-oflthe wall portions. the type having an enclosingjacket. LThe i The portion 22 has on its rear face and adjaapparatus maybe mountedfona base 2 havcent tobut below the member 26, a hookbr ing corner legs`8 and'crossrails 4. HThe caslooking member 28, which comprises awsnbing 5'of the ,ash-pit rests upon the rails 4 which support the apparatus. The front of the casing 5 is open and secured thereto, as by bolts 6,:or the like, is a supporting plate-like frame Fig. 6 is a detailpvi'ew of a hinge member.

end of which extendsxupward a part or arm 30. The Opening 8 is adapted to be closed by a door or closure member lhaving a hinge member 32 which preferably comprises a the-ash-pit'. The

The hinge member 32 is preferably secured to the door member by bolts, or the like 36. The arm members 33, 34 project through the opening 8, and

each preferably comprises a substantially arcuate portion, designated, respectively, 37, 38, extending from the door member, and a portion designated, respectively, 39, 40, substantially radial to its arcuate portion. The portions 39, 40 terminate in bearing parts 41, 42, The portions 39, 40' are of such length that when the door member is in closed position, the bearing parts 41, 42 will lie between the plate member 26 and wall portion 20 and between plate member 27 and wall portion 21, respectively. Through the plate member 26, bearing part 41, and wall portion 20, are substantially vertically alined apertures 43, 44, 45, respectively. Through the plate members 27, bearing part 42, and wall portion 21, are substantially vertically alined apertures 46, 47, 48, respectively. Extending through the apertures 43, 44, 45, is a. hinge pin or pintle 49 which is supported by the wall portion 20 and plate member 26, and which in turn supports the hinge arm 33. The pin 49 is held or locked in position by a member or arm 50 which extends laterally therefrom at lits inner and lower end and seats on the hook part 29 between the hook part 30 and the portion 22. Extending through the apertures 46, 47, 48 is a hinge pin or pintle 51 having an eye 52, or other enlargement, at its inner and upper end, and which seats on the plate member 27. The plate member 27 and wall portion support the pin 51, which in turn supports the hinge arm 34. The apertures 44 and 47 are of suflicient diameter to permit free swinging of the hinge member 4on its pintles. If desired, washers 52', or the like, may be placed between the arm member 33 and plate member 26 and between the arm member 34 and the wall portion 21.

In order to remove the closure member 31 from the supporting frame member 7, the plate member 23 is removed by unscrewing the screws 25, provided the enclosing jacket 53 is not in place; but if such is the case, the door may be swung to open position, as in Fig. 5. In either case, access may be had to the pins 49 and 51. Removal of pin 51 merely requires that it be vertically withdrawn, as is apparent. .Removal of pin 49, however,

requires that the pin be lifted or moved from its normal position, des1gnatedA,Fig. 2, further into or through the apertures 43, 44, 45 until the lateral arm 50 is above the upright arm 30, as indicated by the dotted line position designated B, and then swung forward from the plane of the drawing, Fig. 2, or from right to left of Fig. 3, so that arm 50 will be out of opposing relation to the hook member 28, whereupon the pin 49 may be f withdrawn by dovvnward movement from the apertures 46, 47, 48, thus freeing the door from the supporting frame member. To mount the door on the supporting frame member merely requires a reversal of the above outlined steps by which the pins 49 and 51 are removed.

lVhat I claim and desire to secure by ters Patent of the United States is:

1. In a heating apparatus, a door frame having top, bottom and side frame members, one of said side frame members having substantia-lly horizontal spaced members, an upwardly facing hook member positioned beneath said spaced members, said spaced members having alined bearing apertures therethrough Offset horizontally from said hook member, a closure member cooperable with said frame and having a hinge arm rigid therewith, the free end of said arm extending Letbetween said spaced members and having an aperture alined with said apertures, a hinge pin longitudinally reciprocable in said apertures and having a lateral arm Cooperable with said hook member where'by said pin is held against withdrawal from said apertures.

2. In a heating apparatus, a door frame having top, bottom and side frame members, a closure member cooperable With said members, al hinge member having vertically spaced substantially parallel arms and being rigidly Secured to said closure member, a bar member rigidly connecting said arms atl said closure member, spaced substantially horizontal hinge pin receiving members rigid with said frame and lying respectively above and below each of said arms, a hinge pin extending through each of said arms and its adjacent pin receiving members, and means normally preventing withdrawal of one of said pins.

3. In a heating apparatus, a cast metal door frame having top, bottom and side frame members, one of said side frame members having an aperture therethrough with a surrounding flange, a plate portion extending across said aperture adjacent and substantially parallel to the top portion of said flange, a closure member cooperable with said frame and having a hinge member, the free end of said hinge member extending into said aperture between said fiange and plate portion, and a hinge pin extending through said plate portion, said hinge member and said fiange Whereby to provide a pintle for said closure member.

4. In a heating apparatus, a cast metal door frame having top, bottom and side frame members, one of said side frame members having an aperture therethrough with a surrounding flange, a plate portion extending across said aperture adjacent and substantially parallel to the top portion of said flange, an upwardly facing ho'ok member rigid with said one side member and posi- Signed my name.
